The Balloon Analogue Risk Task (BART) was administered to a sample of 26 high school-aged adolescents to test the utility of the BART as a behavioural measure of risk-taking propensity. Data indicate that riskyness on the BART was related to self-reported engagement in real-world risk-taking behaviours. These data replicate and uniquely extend past research to an adolescent sample, suggesting that the BART may be a useful addition to self-report batteries for the assessment of risk-taking behaviours in adolescents.
